FROM: Alyson Fauske, Assistant City Engineer 0� DATE: February 11, 2013 SUBJECT: 2013 Street Improvement Project Nos. 13 -01 -3 & 13 -01 -4: Horseshoe - Indian Hill and Sandy Hook Areas Public Hearing PROPOSED MOTION "The City Council orders the preparation of plans and specifications for the 2013 Street Improvement Project Nos. 13 -01 -3 and 13 -01 -4, Horseshoe - Indian Hill and Sandy Hook Areas. City Council approval requires a simple majority vote of the City Council present." BACKGROUND At the September 10,2012 work session, staff reviewed with Council the proposed 2013 Street Improvement project areas. Staff also discussed with the Council the need to make improvements to more local streets then are currently budgeted for in the Capital Replacment Plan. On September 24, 2012, the City Council authorized the preparation of the feasibility report. On November 7, 2012, staff held an Open House for the Greenwood Shores neighborhood; approximately 40 residents attended. On November 14, 2012, staff held an Open House for the Horseshoe /Indian Hill and Sandy Hook neighborhoods; approximately 40 residents attended. On November 15, 2012, staff held an Open House for the Melody Hill neighborhood; approximately 30 residents. On December 10, 2012, the City Council accepted the feasibility study for the proposed 2013 street improvements. Chanhassen is a Community for Life - Providing for Today and Planning for Tomorrow 2013 Street Improvement Project 13 -01 February 11, 2013 Page 2 OVERVIEW, PURPOSE AND NEED FOR IMPROVEMENTS Every year the City considers streets that are in poor condition to be rehabilitated or reconstructed. For the 2013 Street Rehabilitation Project, staff is proposing to rehabilitate approximately 4.6 miles of streets. The street segments within the proposed project were identified by the City's Pavement Management software in conjunction with site investigations and are shown below. Wody Hill Horseshoe Curve & Indian Hill Road S d Greenwood Shores ML.., � t n,t Sandy Nook 3 .r kb or rtu , BuJie�Brct The public hearing for the Greenwood Shores area was held on January 14, 2013. The public hearing for the Melody Hill area was held on January 28, 2013. HORSESHOE CURVE /INDIAN HILL PROJECT AREA The streets within this project area were constructed in 1978 and were sealcoated in 1994, 1999 and 2007. Heavy patching of the roads took place in 2011. The estimated PCIs presented with the feasibility study are shown on the map. The City's pavement management consultant surveyed Horseshoe Curve and Indian Hill Road in November to determine the actual PCI. The score for Horseshoe Curve was 16 and Indian Hill Road was 13. A full depth mill and a 3" overlay is proposed. No major storm sewer improvements are proposed with this project area since the area is essentially fully developed. g: \eng \public \_2013 projects \13-01 street rehab \021113 public hearing - horseshoe - indian bill -sandy hook.doc 2013 Street Improvement Project 13 -01 February 11, 2013 Page 3 The watermain within this area is ductile iron pipe. There are no known watermain breaks within this area. It is recommended to replace the bolts on the valves and some hydrants at this time. Attaching anode bags to the watermain at every watermain excavation is also recommended. The sanitary sewer is ABS pipe. Detailed review of the sanitary sewer televising reveals that two sections of pipe in Horseshoe Curve and the sewer within Merry Place should be replaced due to cracks in the pipe. In general, resident questions /concerns related to drainage and assessments. These questions were answered at the meeting or with follow -up correspondence. SANDY HOOK & SANDY HOOK CIRCLE PROJECT AREA Most of the streets in the Sandy Hook area were constructed in 1975. Sandy Hook Circle was constructed in 1981. Sandy Hook Drive and Sandy Hook Circle were sealcoated in 2001 and heavily patched in 2000 and 2011. Dakota Avenue and Dakota Circle were sealcoated in 1995 and 2001 and heavily patched in 2011. Cheyenne Trail was sealcoated in 1995 and heavily patched in 2001 and 2011. Despite the maintenance history in the project area, the pavement condition is still poor with the estimated PCIs between 13 and 34. yy� A t� m * n A The preliminary design that was discussed at the neighborhood meeting for Sandy Hook Circle was a full depth mill and overlay. Since the neighborhood meeting, the soils investigation report has been completed. Based on the soils report and onsite investigation, staff is now recommending Sandy Hook Circle be edge milled and a 2" overlay be paved. These streets have curb and gutter g: \eng \public \_2013 projects \13 -01 street rehab \021113 public hearing - horseshoe - indian hill -sandy hook.doc 2013 Street Improvement Project 13 -01 February 11, 2013 Page 4 and have an adequate aggregate base section. The other areas in this neighborhood are still recommended to have a full depth mill and overlay. This design change has also lowered the proposed assessment amount for Sandy Hook Circle. Due to the fully- developed condition within this area, there is little opportunity to install stormwater management facilities within the area. Staff is planning to meet with the residents along the Sandy Hook Road cul -de -sac and Dakota Avenue to discuss opportunities to install rain gardens. A map of the existing storm sewer and drainage area boundaries is shown below. The watermain within this area is ductile iron pipe. There are no documented watermain breaks. It is recommended to replace the bolts on the valves and some hydrants at this time. Attaching anode bags to the watermain at all excavated watermain areas is recommended. The sanitary sewer in this area is PVC pipe. The sanitary sewer has been televised to determine if there are any structural deficiencies and/or inflow /infiltration issues with the pipe. One section of pipe within Dakota Avenue will be sealed with the inflow /infiltration project this year. The remainder of the pipe is in good condition. In general, resident questions /concerns related to drainage and assessments. These questions were answered at the meeting or with follow -up correspondence. PROJECT FUNDING Special assessments to the benefitting properties are proposed to pay for a portion of the proposed 2013 Street Improvement Project No. 13 -01 per the City's assessment practice. The remaining project costs are proposed to be paid from City funds. All the utility improvements are proposed to be paid for by the associated utility fund. The preliminary funding for all project areas is shown below: Funding Source Estimated Total Project Cost Budgeted Assessments/Revolving Assessment Fund $1,689,900 $1,695,000 Storm Water Management Fund $119,200 $125,000 Water Utility Fund $174,870 $175,000 Sanitary Sewer Utility Fund $142,820 $150,000 $2,126,790 $2,145,000 Each project area would have its own proposed assessment. g: \eng \public \_2013 projects \13 -01 street rehab \021113 public hearing - horseshoe - indian hill -sandy hook.doc 2013 Street Improvement Project 13 -01 February 11, 2013 Page 5 HORSESHOE/INDIAN HILL AREA ESTIMATED PROJECT COSTS Street costs (revolving assessment): Storm sewer: Watermain: Sanitary sewer: The estimated assessment is calculated as follows: Total estimated street cost, Horseshoe /Indian Hill area: 40% of $154,879.68 is assessed: Number of assessable units: Estimated assessment $61,951.87 - 46 units: $154,879.68 $0.00 $48,140.00 $46,566.50 $154,879.68 $61,951.87 46 $1,346.78/unit The estimated unit assessment presented at the November, 2012 open house was $1,692.61. SANDY HOOK AREA ESTIMATED PROJECT COSTS Street costs (revolving assessment): $442,826.62 Storm sewer: $1,846.00 Watermain: $75,280.00 Sanitary sewer: $7,285.00 $527,337.62 As mentioned previously an edge mill and overlay is proposed for Sandy Hook Circle since the street is newer and has curb and gutter, therefore it is proposed that the properties with access to Sandy Hook Circle be assessed separately from the remainder of the Sandy Hook area project. The estimated assessment for the Sandy Hook area (excluding Sandy Hook Circle) is calculated as follows: Total estimated street cost, Horseshoe /Indian Hill area: $375,086.44 40% of $375,086.44 is assessed: $150,034.58 Number of assessable units: 55 Estimated assessment $150,034.58 - 55units: $2,727.90/unit g:\eng\public\ projects \13 -01 street rehab \021113 public hearing - horseshoe - indian hill -sandy hook.doc 2013 Street Improvement Project 13 -01 February 11, 2013 Page 6 The estimated assessment for Sandy Hook Circle is calculated as follows: Total estimated street cost, Sandy Hook Circle: $67,840.18 40% of $67,840.18 is assessed: $27,136.07 Number of assessable units: 18 Estimated assessment $27,136.07 - 18 units: $1,507.56 /unit The estimated unit assessment presented at the November, 2012 open house for the entire Sandy Hook area was $2,972.10. Proposed terms for the assessments are eight (8) years at 6% interest. The interest rate will be adjusted at the time of awarded contract based on the prime rate plus 2 %. The cost estimates includes 5% indirect costs and 8% contingency. Public hearing notices have been mailed to property owners in both areas.

Current 5 -year plan shows the following neighborhood areas: 2013 - Greenwood Shores, Melody Hill neighborhoods, Horseshoe Curve, Indian Hill Road, Sandy Hook Road neighborhood, Rice Marsh Lake trail loop extension 2014 - Dartmouth Drive, Cypress Drive and Kiowa Trail 2015 - Carver Beach area (south and west of Carver Beach Road), Ches Mar Drive, Lone Cedar, Saddlebrook Pass neighborhood MSA - Park Road, Park Court and Park Drive 2016 - North Manor Road, Washta Bay Road, Tanagers Lane, Sandpiper Trail, Piper Ridge Lane and Minnewashta Woods Drive MSA - Kerber Blvd 2017 - Flamingo Drive area and 96th Street MSA - Lake Drive Justification I The City uses a Pavement Management System to monitor the condition of the City streets. While proper preventative maintenance extends the life of the street and is cost effective, a street will eventually deteriorate to a point that further maintenance is no longer cost effective. Rehabilitation projects extend the life of the street. In cases with utility or poor sub grade needs to be replaced or where streets have deteriorated to a point where rehabilitation will no longer be practical reconstruction of the street is necessary. A feasibility study is written to consider the merits of the project and scope of work.

The program also detects and eliminates points of entry of ground water and surface water into the City sanitary sewer system Projects have been identified from the 2006 Inflow and Infiltration Report. The projects were reviewed by Metropolitan Council and approved in Iieu of surcharge fees. Justification City staff has identified numerous older sewer lines that are in need of repair. The City of Chanhassen pays the Metropolitan Council for sewage treatment. Those payments are based on the amount of flow generated by the City of Chanhassen. Surface water and ground water that makes its way into the system either through breaks, displaced joints, manhole covers, or private connections to the system increase the amount charged to the City for sewage disposal and increasing the load on the City's lift stations.
